SAIL-BOAT.

SPECIFICATION formingpart Of Letters Patent N0. 685,943, dated November 5, 1901.

Application filed February 28, 1901. Serial No- 49,309. (No model.)

To all whom it may concern Be it known that 1, JAMES P. PooL, a citizen of the United States, residing in the bor ough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Sail-Boats, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertaius to make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

My invention has reference more particularly to a saihboat having asail that stands crosswise of the hull of the boat as distinguished from a sail that can be turned fore and aft.

My invention consists in the various novel and peculiar arrangements and combinations of the several parts of the apparatus, all as hereinafter fully described and then pointed out in the claims.

, I have illustrated types of my invention in the accompanying drawings, wherein- Figure 1 is a View. of a sail-boat embodying rny improvements, the View being taken from the stern of the boat with the sails full set standing abeam. Fig. 2 is a plan view of the sail-boat shown in Fig. 1, but with the sails trained at an angle across the boat instead of standing normal thereto. The dotted lines in this figure show the different positions into which the sails may be adj usted. Fig. 3 shows a construction in which a modified form of the sails is used.

Referring to the drawings, in which like numbers of reference designate like parts throughout, 2 indicates the hull of the boat, which may be of any desired shape. In the center of the hull is fixed a mast 3,upon which are mounted a pair of swinging frames, one for each sail, and each constructed substantially alike, so that a description of one will serve for both. These swinging frames comprise an upper arm 4 and a lower arm 5, each of which is mounted to swing freely about the mast at its innerend, while the outer ends of these arms are connected together by a strong stay or cable or rod 6. The sail 7 is arranged within the swinging frame by having its outer edge attached to the stay 6 by means of a set of loops or rings 8, which freely move on the stay,while the lower end of the sail is secured to a swinging member or arm 9, which at its outer end is provided with an eye 10 for receiving the stay 6, on which it is thus hinged. The upper end of the sail is secured to a similar swinging member or arm 11, having an eye 12 at its outer end,through which the stay passes and on which the arm freely swings. This upper swinging sail-arm 11 is provided with halyards 13, which pass through suitable pulleys or eyes 14, secured upon the swinging frame member 4, and the lower ends of which are attached to a fixed point 15 on the deck.' The outer end of the swinging frame member 4 has connecting with the mast-head a cable or rope 16 for suspending the frame, while the inner end of the swinging sail-arm 11 is supported from above by a suitable halyard 17, which is shown in dotted lines in Fig. l and which is secured at its lower end at the point 18 on the mast. From this construction itwill be seen that a swinging frame or rigging upon each side of the mast can be swung independently of the other, and by giving each its proper angular adjustment and also setting the sail within the plane of each frame the sail upon opposite sides of the mast may be set in the same plane, and which plane contains the center of n the mast. This plane, in which both sails are contained, may by angular adjustment of the frames be made to stand at right angles to the boat or diagonallyacross the boat. It. will also be noted thatin addition to each of the swinging frames or rigging being independently adjustable the sail. mounted in each of the frames can be adjusted angularly about a vertical axis at its outer edge and independently of the frame containing it. By

adjusting one of the frames--for instance, the right-hand one shown in Fig. 2-so that it projects'at right angles-that is, it stands on the center line of the boat crosswise, as shown in full lines in Fig. 2--and letting the inner end of its sail go forward out of the plane of the frame, as shown in full lines, the sail is made to assume a position in which its plane extends diagonally across the boat instead of straight across. The sail upon the opposite side of the mast is brought into a different but parallel plane, which also cuts the deck obliquely, by letting the outer end of the swinging frame upon the righthand side swing forwardly into a plane parallel with the plane of the sail upon the other side, as shown in full line. This adjustment brings both of the sails in different but parallel planes. By reversing the adjustment of the swinging frame and its contained sail, respectively, the sail may be made to stand in planes out of parallel and cutting the hull diagonally in reverse direction from that shown in full-line position in Fig. 2, and such adjustment can be made when the boat is to change its tack.

The swinging frame upon each side of the mast is held in its adjusted position by means of an upper rope 19, which extends from the outer end of the swinging arm 4 and passes through an eye 20 on the outer end of the cross-piece 21 and passes down to the deck, where it is secured at a point 22, While the lower end of the swinging frame is held by a rope 23, extending from the outer end of the swinging arm 5 to the fixed point 22 on the deck. These ropes are duplicated upon each side of both of the swinging frames. The upper end of each sail is also provided with a suitable rope 24, which is attached to the inner end of the swinging member 11 and passes through the eye 20 on the end of the cross-piece 21 and passes down to a fixed point 25 on the mast. The lower ends of the sails are each provided upon opposite sides with a rope 26, which is attached to the inner end of the lower swinging member 9 and passes to a point 27 on the deck, to which it is'fixed. By means of these ropes 24 and 26 the sails may be held in position when set in planes out, of parallel.

In Fig. 3 I show a modification in which they sails, which are located at opposite sides of the mast 3, are each set in a frame 28, which at its center of width at the bottom is pivoted at a point 29 on the deck, while at an opposite point at its upper end at 30 it is piv-. oted to a fixed cross-piece 3l on the mast. These two vertical frames are thus constructed to swing on their centers, so that they can each be set in the same plane, which plane contains the center of the mast, or they may be adjusted angularly, so as to, stand in different planes parallel with each other and cutting the deck diagonally. The hull of the boat is provided at two points on the. center line thereof with a pivoted piece 32, which is fixed to a rotary post 33, having a handle 34 for turning it. One of these fins is located fore of the mast and the other aft, and they may each be set in line with each other, as shown in the drawings, or they may be set at the same angle, so as to stand parallel with each other.

In going before the wind the. swinging frames or rigging upon opposite sides of the mastare adjusted in the same plane with each other and so as to stand at right angles across the boat, and the sail in each of the frames is set within the frame, and the two fins 32 are set in line with each other. By swinging the port sail out of its frame, so that its inner end goes well forward, and letting the frame upon the starboard side swing forward the same distance as the sail upon the other side is moved forward the two sails are thrown out of the same plane, but stand in planes which are parallel with each other and which extend diagonally across the boat. If atthe same time the two fins 32 be turned so that their rear ends are swungaround to the starboard side the boat will move off on the port tack. The reverse direction of movement would occur if the sails were adjusted at the reverse angles and if the fins were turned so that their rear ends were swung around to the port side.

I wish to be understood as not limiting my invention to the specific form of the various parts as herein set forth, as various changes may be made therein without, however, departing from the spirit of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-.-
